This invention relates to an information-recording medium that is used for recording information through radiation of energy beam. The combination of the quick release unitary flexible clamp mechanism adjoined to a swivel mechanism allows for small tools, cleaning devices, such as scrub brushes, wall washers, abrasive pad holders, etc. The tail portions of the terminals extend beyond two outermost first walls in the second direction. The stuffed bits are bits that were inserted into the received USB data stream by a transmitter to force data transitions in the received USB data stream. Through the variations of the lighting color of the light emitting object irradiated on the control button, the user can recognize the current usage mode of the digital camera by the color through the light emitting object, thus making operations thereof more recognizable.
